Power surges can take a huge toll on modern day appliances, destroying sensitive and expensive equipment without warning. So, if you have electronic devices, appliances, or equipment that you want to protect, make sure you utilize some form of surge protection.

The following is a quick look at power surges, and how best to prevent your home or business electrical items from being damaged.

What is a power surge?

A power surge is what happens when there’s a sudden increase in the amount of power in the electrical system.

One common cause is the use of high-powered items being used infrequently e.g. a spa, or a heavy duty workshop item. Other means of causing a power surge include faulty wiring, downed power lines, or lightning strikes.

Surge protectors

Protecting your electrical items from power surges is often done by way of a simple surge protector that you plug into your electrical outlet. If the power levels spike about a level deemed acceptable, the surge protector diverts the excess energy into its grounding wire.

This is your best minimum protection for individual or groups of items.

Surge arrestors

But the better way to protect your electrical items is to have a surge arrestor installed to protect all of the circuits in your entire building.

The surge arrestor installation is done at the switchboard, and protects you against surges in power, usually up to around 6000 volts. Higher rated systems are also available if required e.g. commercial situations.
